Product Summary

Gantry cranes have become a widely accepted alternative to overhead bridge cranes. This type of crane is similar to the bridge crane except that it runs on a runway at the floor level. The bridge is supported by a pair of rigid steel legs which are carried by a pair of end trucks along the floor level runway.

Because gantry cranes ride on the ground rather than on overhead runways, they don't require a runway structure. Nor do they usually require concrete foundations. Their installation is fast and simple. Depending on the environment and application, gantry cranes can sometimes provide the same material handling capabilities as a comparable bridge crane system, but with a significant cost savings.

gantry cranes, bridge cranes, overhead crane, are all types of crane which lift objects by a Hoist (device) which is fitted in a hoist trolley and can move horizontally on a rail or pair of rails fitted under a beam. An overhead travelling crane, also known as an overhead crane or as a suspended crane, has the ends of the supporting beam resting on wheels running on rails at high level, usually on the parallel side walls of a factory or similar large industrial building, so that the whole crane can move the length of the building while the hoist can be moved to and fro across the width of the building. A gantry crane or portal crane has a similar mechanism supported by uprights, usually with wheels at the foot of the uprights allowing the whole crane to traverse. Some portal cranes may have only a fixed gantry, particularly when they are lifting loads such as railway cargoes that are already easily moved beneath them.
